i l COMBINED GOAL AND ens RANGE.

To all whomz't may concern.-

Be it known that I, J Arnw S. VAN BUREN, a citizen of the United States, and a resident of Albany, county of Albany, State of New York, have invented certain Improvements in Combined Coal and Gas Ranges, of which the following is a specification.

My invention relates to certain improve;

ments in combined coal: and gas ranges.

' One object of the invention is to construct a burner located outside of the oven and can be exposed or. covered by the hearth plate.

'Afurther object of the invention is to provide the oven door with flue passages communicating with the. interior of the oven and with the ash pit of the coal section of the stove.

'A. still further object ofthe invention is to provide a damper for. checking the draft from the coal section, as wellza's to provide a damper for directing the passage of the products of "combustionieither to the flue or around the oven.

My invention'relates to certain improvements the. burnerfor heating the oven. These objects and other advantageous ends I attain in the'following manner, reference being hadto the accompanying drawingsinwhich: r I

ral gas, as the case may be, the burners befire box 8 of the coal section of the stove and the down flue 9 which leads around the oven and communicates with the under-flue 10. 11- isthe back flue which communicates with the bottom flue 10 under the oven and with the chimney. '12 is a pivoted damper which can be opened to allow the-products of combustion from the coal section of the range to pass directly from'the flue 7 without passing around the oven. Thisdamper is controlled in the ordinary manner, in the present instance from the front of the stove. 13 is a sliding damper, in the present instance, having a hand hold 14 projecting over the top plate of the stove and when this damperis opened it allows air to pass from the gas burner chamber directly into the flue leadingto the chimney so as to check the draft' from the coal section of the 1. range whether the damper 12 is opened or closed." The opening can be made'of 'any area de-' sired by merely slidingthe damperin its ways.

15 is the oven door hinged in the ordinary manner and made as clearly shown'in Fig. 8 having, in the present instance, acentral recess-16 in which the thermometer for indicating the temperature" of theoven is located. 17 is the hearth plate located under the oven door and 18 is the front cover plate for the oven burners; The bottom 19 of the oven terminates some distance back of. the I is shifted to the position illustrated in'Fig.

5,-the flame from the burner 20 will enter the oven between. the door and the bottom plate. When the hearth plate is 'forcedin, it closes this space, as illustrated in Fig. 3,

so that the gas cannot be used until thehearth plate is. withdrawn, as illustrated in Fig. 4;. Y

'38 is a deflecting plate located above the bottom of the oven. The front edge of this plate'comes in contact with the'oven door and rests onza flange 39 on'said door and stops short of the rear of theoven so'thatf theheat frbmthe burner is c'arriedfto the I Sand 5, that thewsection 23 is made eccen-- '20 rear of the oven before being distributed through the oven.

The burner may be of any type desired and is preferably shaped as shown by dotted lines in Fig. 4, having the usual bell end 21 into which the gas pipe extends and in which arethe openings for supplying the burner with air. The amount of air can be controlled by the usual damper. The gas pipe enters this burner in the ordinarymanner and the 'burner'has aaprimary section 22 and a secondary section 23. In the latter section is a series of burner openings 24c through which passes the gas to be ignited; The construction insures a thorough mixture of gas andair before it escapes from the burner.v V Itwill be noticed,uponreferring to Figs.

The burner cover'plate. 18- is made as clearly shown in Fig.6. and has-a flange 25 at each side on which rests the hearth plate 17.

This hearth plate has -undercutlugs 26' which, extend. under this flange and hold the hearthplatefrom tipping. At the frontof. the cover plate 18 is an; extension 18 with which engagethe lugs 27 and 28 on the under side of. the hearth plate so that when,

the hearthplate-is closed. the lug 27 is back off the extension18%.preventing the outward movement; of: the: hearth plate. When the-hearth plate is intheextended position P the lug 8 is in front of the extension 18*,

cover the burneropenings. The hearth plate, isaraisedwhen shifted in either of its two posi-tions.- The rear end'of the hearth plate has av flange. 29 which extends over the section; 2310f the burner and covers the openings 24; when the burner is not in use. The sidezmembers 3O ofthe burner cover plate. 18 are, recessed at 31 and the burner other sectionreceives a lug onthe end of the burner, as clearly shown by dotted lines,

Fig.- 3, but it will'be understood that the burner may be, heldin place in any suitable the essential' features of the invention.

It is desirable toprovidemeans for indieating whether or not the oven burner is ignited and Ipolishtheupper surface of thehearthplate and so locatethe bottom of the door-that it will be some distance above the hearth plate. When the gas; from the burner-is ignited the flame-will be reflected from the hearth plateunder the door and a person using the range caniat any time see the flame reflected in the polished surface of the hearth-and can" detect any uneveness in the burning of the gas without the necessity'of opening-the oven door and interfering with the baking.

heat is. evenly distributed, I form a passage in the oven door by shaping the oven door as indicated in Figs. 3'. and 4t, and locating a plate'32 at the back of the oven door.

The deflector 36 causes the heated air to pass throughv the flue 33 entirely over the: surtaceof the door so asto-insurethe properheatingof the door and thus make the heated air in theioven the door substantially the: same temperature as the airin the other parts. of thev oven.-:

In evens of the ordinary construction the oven is coolest. at the door and, consequently,

the balfing'is more or less. uneven. V

This construction of the oven door isused to advantage eitherwith the coal section of the-range or'withithe gasseetion. When the coal; section is-inuse the heated air from the oven passes intothez ash pitun-der-the gratean-d aldsmateriallyv inthefproper co'inbus tion of the fuel. use, 1t merely relieves. the oven off any unspent gases which'pa-ss: intothe closed-ash When the gas rangeiis in,

pit'of the coal section: and from: this ash-pit through the flue to the chimney so that'it' acts as a ventilator to a.v certain extent for the oven.

While I have described my invention in connection with. a combined: gas and -.coal" range,- it will be=understood that the ar-} rangement for heating the oven: and the ar rangement of the oven door may be used in connection with a gas or coal range, as well as with a combined range without departing from the spirit of the invention.

The damper 13' is also used when. the burners are burning natural. gas and where the top plate is sealed to carry ofl the spent gases from thechamber formed by the easing 4. l

Iclaim: a w o 1. In a combined coal and gas range, the combination of an oven; flues surrounding the oven; a fuel chamber at one side of the oven communicating with the flues a gas] oven near the forwardend thereof-adoor for the oven extending beyond the burner; a sliding hearth plate on a line substantially with the bottom of the oven and arranged to extend over the burner and close the burner opening leading to the oven, the parts being so arranged that the oven gas burner can be used with or without the coal fuel.

2. In a combined coal and gas range, the combination of an oven; a fire pot at one side of the oven; flues extending around the oven and communicating with the fire pot; a door for the oven having flue passages therein, the bottom of the oven terminating some distance back of the oven door; a deflecting plate located above the bottom of the oven and terminating short of the rear thereof, the oven door having an internal, horizontal flange near its lower edge over which the deflecting plate extends; a sliding hearth for the oven and extending under the oven door; a burner extending longitudinally substantially the full width of the oven and under the inner end of the sliding hearth so that when the sliding hearth is tween the burner space and the oven so that the burner can be used to heat the oven and when the hearth is pushed in the burner is cut off from the oven.
